I read this write up somewhere and I thought it is good to share WRT your Q here:-
Once upon a time, it was normal for airlines to recruit cadets through a process which separated the ones with the aptitude and skills best for the position / company concerned, rather than their abilities to procure cash. Times change, it is now very rare for airlines to have senior management / executive financial positions filled by people who care more about the long term sustainability of an operation, than they do about maximizing their next bonus. A fully self-funded cadet program with long term salary sacrifice is just another way of artificially lowering the ticket price and delaying the inevitable exodus of crew. Sure, a uni degree might cost a similar amount. However, does that degree lock you into single company on soup-kitchen wage? This industry has changed a lot, and is changing at its fastest rate ever. At the current rate of erosion of terms and conditions, go ahead, ask yourself where will it be by the time YOU can afford to move on??????????
No guarantee to get a job with the said airlines unless it is part of the agreement before making the payment.
